Strengths of graders and conditional reliability

Research Update: 8 papers on AI in Education you need to know for 2026 In this episode, Ray and Dan provide a rapid-fire rundown of the most significant research papers hitting the AI in Education space so far in 2026. After a series of news-heavy episodes, the hosts catch up on the data behind synthetic avatars, grading accuracy, and the psychological biases we hold against AI. Key highlights include: Synthetic Lecturers: Exploring stakeholder perspectives on digital twins and the emotional reaction to the term Deepfake in academia. The Grading Gap: Why ChatGPT tends to be more sycophantic and generous with weak work compared to human instructors. The Disclosure Penalty: New findings from 16 experiments showing why humans devalue creative writing the moment they know AI is involved. Prompting Hacks: The "Groundhog Day" method 😂 Why simply repeating your prompt twice can boost accuracy across 70 different AI systems. Tools for Researchers: Insights into Jasper Roe's research checklist and the "Paper Banana" tool for automating scientific diagrams. Links to all the research papers discussed
